I'm replacing the valve cover gaskets and I watched your video for the spark plugs so that has helped. Please explain what to remove to get the back valve cover off.

Hello,

You must remove the air filter and intake tube and any brackets or hoses that block access to the valve covers. Then remove the ignition coils and then the valve cover mounting bolts. This generic guide can help walk you through the steps, but you will need to remove the upper intake manifold, make sure you replace the upper intake gasket as well. I have included diagrams below that will help show where to apply the gasket sealant.
